GLOBE-HOLDER FOR LAMPS.-

Application filed August 12,

To all whom it may concern:

Be it known that I, FREDERICK J. HUM- PHREY, a citizen of the United States, residing at Kalamazoo, Michigan, have invented certain new and useful Improvements in Globe-Holders for Lamps, of which the following is a specification.

This invention relates to improvements in globe holders for lamps.

In using the term globe holders in this application, I intend that it shall be considered to embrace shades, reflectors and the like, where they are supported in substantially the same manner, as my holder is adapted for holding shades, reflectors and the like, as well as globes.

The main object of this invention is to provide an improved globe holder which is simple and economical in structure, easy to operate, and one which effectively supports the globe in a central position.

Further objects, and objects relating to structural details will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification. The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing forming a part of this specification, in which:

Figure I is a front elevation of a structure embodying the features of my invention. Fig. II is a horizontal section on a line corresponding to the broken line 22 of Fig. I. Fig. III is an enlarged detail vertical section on a line corresponding to line 33 of Fig. II.

In the drawing similar reference characters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring to the drawing, the body or casing l of the lamp which may be of any suitable design, is provided with a cylindrical globe holder portion 2 at its lower end, having an inturned flange 3. The globe is provided with an out-turned flange 5 at its upper end which is inserted through the globe holding ring 6 so that the ring clasps the globe below the flange. The globe is spherical. It may be of any desired shape,

and, as stated, by the term globe I contemplate reflectors, shades and the like.

The cylindrical portion 2 of the body is provided with a slot 7 at the rear, opposed side slots 8, and a pair of front slots 9. These front slots are spaced as shown in Fig. I, which is a front view. The slots 7 and 8 are arranged in the same horizontal plane. The slots 9 are arranged, one mainly above the central horizontal plane of the rear and side slots, and the other mainly below such plane.

The globe supporting ring 6 is formed of wire, the ends of the wire being crossed within the body member and arranged through the front slots 9. The supporting ring 6 is provided with supporting fingers at the sides and rear, the fingers being formed by loops in the wire. These fingers 10 are straight and all he in the same plane. This permits their being easily inserted through the slots and allows them to move freely therein. The supporting ring is contractive; that is, it tends to contract or collapse so that it clasps the globe with a spring action. This contractive quality of the ring holds the side fingers 1O normally against the front ends of the slots 8, the fingers constituting stops limiting the contraction of the ring. The ends of the ring engage the outer ends of the slots 9 owing to the contractive tendency of the ring and this centers the ring so that it is held properly centered and the globe is supported in a central position.

When it is desired to open the ring to receive or release the globe, the finger pieces 11, which are formed by coils in the ends of the wire, are grasped between the thumb and finger and pressed together, which expands the ring. When the ring is expanded in this manner, the rear supporting finger 10 moves rearwardly in the rear slot 7, while the side supporting fingers 10 move rearwardly in the side slots 8. As soon as the supporting ring is released, it contracts to its normal condition, embracing the globe, or if no globe is present it contracts until the fingers 10 engage the front ends of the slots 8.

The front slots 9 are quite short and close together. The ends of the ring are crossed between these front slots and are somewhat distorted from a true circle. This, however, does not prevent the globe being properly supportedvan'd centered fThispermjits the finger pieces 11 being normally close to. gether so that they can be conveniently grasped. When the finger pieces 11 are pressed toward each other, the ends of the ring engage the inner ends of the slots '9 which causes the ends of the ring to move longitudinally in the slots rather than to swing therein in expanding the ring. WVhen the finger pieces are released, the ends of the ring.bearingagainst the outer endsof the slots 9 cause the ends to move longitudinally when the ring contracts and'the. ringvis also properly centered. a

The arrangement of the fingers and the ends of therings through the slots as described, supports the ring throughout, so that there is no tendency for the ring to tilt even though it be'used on heavy globes, and

comparatively light Wire is found to be entirely satisfactory.

My improved globe holder is very simple and economical in structure, the parts being simple and economical to produce and very easily assembled. ,It is also easily operated and effectively supports the globe in a central position. i

Having thus described my invention, What i I claimas new and desire to secure by Letters Patent is:

1. In a globe holder for lamps-the combination of a cylindrical body and a contractive ring formed of wire arranged within the body to clasp a globe, said body being provided with horizontal slots at its rear, sides and front, the slots at the rear and sides being in the same horizontal plane, v.

those atthe sides being 0 posed, there being a pair of slots at thef font, one disposed mainly above and the other-mainly below the central horizontal plane of the slots at the side and rear, theends of the ring being crossed within the body and arranged through the front slots tangentially of the body and normally in engagement with the outer ends of the slots, said ring having Copies of this .patent may be obtained for loops atthe sides andrear constituting supporting fingers engaging the rear and side slots, the side fingers being normally in I engagement with the front ends of the side slots and constituting stops limiting the contraction of the ring.

2. In a globe holder for lamps in combination of a cylindrical body member having horizontal slots at the rear, sides and front,

the rear and "side slots being in the same horizontal plane, the side slots being opposed, there being a pair of spaced front slots, and a contractive ring formed of wire arranged 'within the body with its ends crossed and disposed through said front 4 slots tangentially 'ofthe body and normally in engagement with the outer ends of the slots, the ring being provided with straight supporting fingers engaging the side and rear slots.

3. In a globe holder for lamps, the combination of a cylindrical body member having horizontal slots at the rear'sides and front, the side slots being opposed, there being a pair of short front slots disposed close together, and a contractive ring formed of wire arranged within the body with its ends crossed between the front slots and disposed through said slots tangentially of the body and normally in engagement with the outer ends of the slots, the ring being provided with supporting fingers engaging the sides five cents each, by addressing the Commissionerof Patents, Washington, D.
